What are the reasons for the low temperature at the furnace head of a 4 cubic meter ramming coke oven?
Thread Content
I would like to ask my senior colleagues: the coke oven I work in is a 4.3 cubic meter rammed regenerative coke oven, and when using blast furnace gas for heating, the temperature at the oven head remains low; it’s impossible to increase this temperature. I would appreciate some guidance from the seniors.
I don’t know how many years your coke oven has been in use. Is there any leakage? If so, it may be caused by a leak of gas blocking the chute or regenerator. If this results in a low burner temperature, there are basically no good solutions. But some measures can be taken to alleviate it. 1. Strengthen the spraying at the furnace nozzle area of the carbonization chamber. Seal the furnace body to reduce leakage. 2. Raising the pressure in the gas collection pipe allows raw gas to leak from the carbonization chamber into the combustion chamber in multiple directions, which also serves a sealing purpose. 3. Reduce the suction in the smoke branches, thereby increasing the static pressure of gas at the burner area and allowing more gas to flow in. 4. The key is to remove the adjustment bricks from nozzles 1 and 2 in order to reduce resistance in the chute. 5. Some coking plants also install a separate burner heating system for supplementary heating.
1. Check the suction at the top of the regenerator to see if it is too high. Consider increasing the opening degree of the air inlet or reducing the suction at the top of the regenerator. 2. Check for any leaks around the sealing walls of the regenerator and on the front side of the incline
